A successor to his previous label Beat Club, it has operated as an imprint of Def Jam Recordings since 2019.

MMG's third release was OneRepublic's debut album Dreaming Out Loud on November 20, 2007, from which the single "Apologize" hit #2 on the Billboard Hot 100.

The move to the new label was due to his involvement in the success of Michael Jackson's second posthumous album Xscape.

Most of the artists signed to Mosley Music Group will have their future recordings handled by Epic with the exception of OneRepublic, who will remain at Interscope.
